Good question - I too some times think about it and the answer I found is that, there is no doubt that thoughts are produced from brain but in way to differentiate the 'intellectual thinking' and 'emotional thinking' the HEART term has evolved.
One specific reason for that is that heart is the centre for pumping the blood to the whole body, it is one which does not stop at any time during the life . . . and it is highly flexible to human emotions. Every thought and feeling has a deep impact on the speed and rhythem of heart. For example if some one is emotionally peaceful then the heart beats highly slow and rhythemic, and if someone is agitated or furocious then the heart rate is fast and rhythem is highly unstable.
Since the emotions has a strong impact on the heart beat... in general terminology it is said like heartful, by heart, true heart, sweet heart etc.
But that does not imply that heart can think. it is only the discrimination of intellectual thinking and emotional feelings

LOL... Except for the great number of morons loose on the streets, I'd be willing to risk that the preponderance of people are generally pretty certain that their hearts are not thinking organs and that their brain is capable of functioning on both an emotional and an intellectual level. There might even be a few folks around who recognize the brains ability to act on the primal and the wholly autonomic levels as well.
I hope this little bit of knowledge has helped you settle the matter and that your heart can rest a bit easier on this subject. LOL

Head-Heart Interactions
Traditionally, the study of communication pathways between the "head" and heart has been approached from a rather one-sided perspective, with scientists focusing primarily on the heart's responses to the brain's commands. However, we have now learned that communication between the heart and brain is actually a dynamic, ongoing, two-way dialogue, with each organ continuously influencing the other's function. Research has shown that the heart communicates to the brain in four major ways: neurologically (through the transmission of nerve impulses), biochemically (via hormones and neurotransmitters), biophysically (through pressure waves) and energetically (through electromagnetic field interactions). Communication along all these conduits significantly affects the brain's activity. Moreover, our research shows that messages the heart sends the brain can also affect performance.
The heart communicates with the brain and body in four ways:
• Neurological communication (nervous system)
• Biophysical communication (pulse wave)
• Biochemical communication (hormones)
• Energetic communication (electromagnetic fields)
The studies described in this section probe several of these communication pathways, looking specifically at how the brain responds to patterns generated by the heart during positive emotional states. The first two studies focus primarily on neurological interactions, demonstrating that the afferent signals the heart sends the brain during positive emotions can alter brain activity in several ways. In the first study, we find that cardiac coherence can drive entrainment between very low frequency brainwaves and heart rhythms, thus further expanding our understanding of the physiological entrainment mode described in the previous section. In the second study, we learn that coherent heart rhythms also lead to increased heart-brain synchronization. The implications of these findings are explored in the third study, which shows that in states of high heart rhythm coherence, individuals demonstrate significant improvements in cognitive performance.
Taken together, the results of these studies demonstrate that intentionally altering one's emotional state through heart focus modifies afferent neurological input from the heart to the brain. The data suggest that as people experience sincere positive feeling states, in which the heart's rhythms become more coherent, the changed information flow from the heart to the brain may act to modify cortical function and influence performance. These findings may also help explain the significant shifts in perception, increased mental clarity and heightened intuitive awareness many individuals have reported when practicing the HeartMath techniques.
The final two studies in this section are concerned with energetic communication by the heart, which we also refer to as cardioelectromagnetic communication. The heart is the most powerful generator of electromagnetic energy in the human body, producing the largest rhythmic electromagnetic field of any of the body's organs. The heart's electrical field is about 60 times greater in amplitude than the electrical activity generated by the brain. This field, measured in the form of an electrocardiogram (ECG), can be detected anywhere on the surface of the body. Furthermore, the magnetic field produced by the heart is more than 5,000 times greater in strength than the field generated by the brain, and can be detected a number of feet away from the body, in all directions, using SQUID-based magnetometers (Figure 12). Prompted by our findings that the cardiac field is modulated by different emotional states (described in the previous section), we performed several studies to investigate the possibility that the electromagnetic field generated by the heart may transmit information that can be received by others.
The Heart's
Electromagnetic Field
Figure 12. The heart's electromagnetic field--by far the most powerful rhythmic field produced by the human body--not only envelops every cell of the body but also extends out in all directions into the space around us. The cardiac field can be measured several feet away from the body by sensitive devices. Research conducted at IHM suggests that the heart's field is an important carrier of information.

Head-Heart Interactions
Thus, the last two studies summarized in this section explore interactions that take place between one person's heart and another's brain when two people touch or are in proximity. This research elucidates the intriguing finding that the electromagnetic signals generated by the heart have the capacity to affect others around us. Our data indicate that one person's heart signal can affect another's brainwaves, and that heart-brain synchronization can occur between two people when they interact. Finally, it appears that as individuals increase psychophysiological coherence, they become more sensitive to the subtle electromagnetic signals communicated by those around them. Taken together, these results suggest that cardioelectromagnetic communication may be a little-known source of information exchange between people, and that this exchange is influenced by our emotions.
HEAD-HEART ENTRAINMENT:A PRELIMINARY SURVEY
Rollin McCraty, PhD, William A. Tiller, PhD and Mike Atkinson. In: Proceedings of the Brain-Mind Applied Neurophysiology EEG Neurofeedback Meeting. Key West, Florida, 1996.
Figure 13. Illustrates the entrainment that can occur between the HRV and EEG waveforms. The lefthand graphs show the time domain signals for the HRV and the EEG (brainwaves), while the righthand panels show the frequency spectra during the entrained state. Note the large peak at the entrainment frequency (~0.12 Hz) in both the HRV and the EEG while the subject is in the entrained state.
Key findings: As people learn to sustain heart-focused positive feeling states, the brain can be brought into entrainment with the heart.
Summary: This study examines in further detail the entrainment mode of cardiac function described previously in "Cardiac Coherence: A new noninvasive measure of autonomic nervous system order." In the previous investigation it was found that when the heart is functioning in the entrainment mode, there is a marked shift in the HRV power spectrum to the resonant frequency range of the baroreceptor feedback loop (around 0.1 Hz), and frequency locking between the HRV waveform, respiration and pulse transit time occurs. The present study shows that as individuals learn to maintain the entrainment mode through sustaining sincere, heart-focused states of appreciation or love, the brain's electrical activity can also come into entrainment with the heart rhythms. Figure 13, below, shows an example of entrainment occurring between a subject's HRV and the very low frequency band region of the electroencephalograph (EEG) recordings after the individual practices the Freeze-Frame intervention for 5 minutes. There is nearly a hundred-fold increase in power in the 0.1 Hz frequency range of the HRV power spectrum after the Freeze-Frame intervention and a correlated 4 to 5- fold increase in the EEG signal power in that same frequency range. Our present hypothesis is that a strong and sustained increase in baroreceptor system activity leads to greatly increased coupling between the heart (HRV) and the brain (EEG) via nerve conducted signals and increased coherence in the vascular system. The results of this experiment provide one example of how increasing coherence in the heart rhythms, by intentionally generating positive emotions, can alter brain activity.
i know huge artical it is,but this tells heart can also think it's nt jus our emotional state seart is as imp entity as brain...but yes brain has edge on it dur to it's controll on our whole body...heart together with brain help in thinking process
i'm giving source of this artical u can find diagrams on this link for more clearity
